    I have very good battery life and am on verizon. Typically have 13 to 14 hours with 40% to 55% or so towards the end of the day which is with a good amount of typical use (GPS to and from work, emails all day long, bluetooth on and off as i drive, voice calls, texting/msging with whatsapp, fb mess, sms, mms, instagram/twitter/fb browsing while killing time - just no games or youtube watching during the workweek - and streaming music for 30 mins or so). I was getting a little impatient with some light/medium lag - Ive only had my N4 for 3 weeks or so it should not be lagging at all! pisses me off anyhow I switched the runtime setting from Dalvik to ART and although it did seem to help a bit on the lag (but a few apps would shut down so i had to switch back) I def noticed an even greater battery life. I had it on ART for 3 days and roughly i would say 20% to 30% battery battery life (complete guestimate but it was enough to notice for sure). I wish it were stable it helped with lag a bit and boosted battery life a noticeable amount. My N3 Had no lag for about 6 months - this N4 has it almost right out of the gate. Wish I knew the culprit.

    If that is true with art theoretically that would mean when we get the 5.0 update battery life will improve since lollipop runs off of art from the get go. I got 7 hours of screen on time yesterday, good enough for me! I am getting impatient with Samsung not stocking their battery and charger though I use my phone enough away from home to justify carrying a spare around.

    I posted a week ago that my battery life wasn't so great, but since last Saturday I've been getting a solid 10 hours. I consider that good, because I am a heavy user, throughout the day.

    I'm closing in on my two week period....I unplugged my phone at around 1230 today, it was at 100% I'm now at 78%. Granted I don't think I've closed the screen once....does this seem normal or should I maybe look into getting a new one?

    I don't know how times show here. Whether it is 30 or 90 minutes you mean you don't need a new battery. You need the GSAM app and to study what it tells you. Everyone on this thread who thinks they have problems with a battery likely have problems with the apps they are using. I had a problem and I figured out which app it was. It's just not mathematically possible to have as many defective batteries or devices as people think there are. Has anyone ever gotten a bad battery for anything else? I have to believe anyone with Android System sucking more juice than Screen does is having an app problem. If you don't want to read all this stuff (not you specifically logik) then swap batteries, see the same thing happen, swap phones, see the same thing happen and THEN get GSAM and study...

    So logik, mine with great stats has system and kernel about 2 points apart. Looks like you have something in Android System that's sucking up power. I'd keep looking for that and try to see what it is.

    From several devices now and hundreds of posts I believe Android System should never be higher than screen and certainly not nearly double kernel. I know screen isn't on the one you mentioned. I am thinking of the later one there. It's not scientific and I am not a developer. I just read all this stuff.

    How to figure out for me is to look at each app and try to find similar cases outside this forum. XDA is more technical and Google has everything. It's trial and error. Keep figuring out what it isn't until the problem stops.

    That's 2.5 hours of screen time and practically 13 hours being unplugged. For a heavy user like myself, that is great battery life. That is with NFC on, wifi, Bluetooth , and 6 email addresses syncing with the phone.

    I stand corrected...that IS good. Obv misread screen time as off charge time. Sry.

    I have had a Note 3 for a year. I changed to a bigger capacity battery to help battery life. Actually, now that I have changed back to the Stock Original Battery things are really much better.

    The camera still dies. I turned off locations related to camera and re boot the phone after taking a picture. That seems to stop the camera from sucking down the battery life.

    I use lux light, greenify, and greenpower on my rooted Note 3. I rooted it to do battery calibration basically.

    After all this, I can now say that the Note 3 runs better than my LG G3 but not as good as my One Plus One.

    Gents all you need to do is enable developer options and then select limit background processes to 4. Fixed mine. On 66 % with 20 hrs moderate usage yesterday I hadn't done this used it less and 40% at lunchtime (charged in morning)

    I actually thought my battery life wasn't good, but then again, I have nothing to compare this new phone too. Im coming from a iphone 5 which of course didn't have a great display like this one, cpu, ram, etc..

    Im getting 5 hours or so of screen time. Im thinking of doing a reset like some of the other guys have done.
    screen brightness is around 75%

    I had forgotten about that nugget, too. Thanks for the reminder.

    But it is also important to understand what background processes really are and how they work.

    Here's a post from another forum (not mine, another user):

    limiting Android’s background processes using option in the Developer section won’t stop applications that would normally run in the background from running. Your mail client will still run periodically to check mail, if it’s configured to do that. Applications like Facebook, Google Location Services, Tasker… will still be able to do so. So next time each application needs to start all over again, Android has to load the application from scratch, this uses more power and takes longer than running it again when the process was in memory. What you are referring to is Cached background process limit, allowing applications to stay cached will help performance and constant re-loads, especially considering that if there is plenty of RAM.
    Because this is a development option, it can also trigger some rare bugs in certain applications, also can cause a loop of services restarting each other to check for updates like google calendar updates.
    Said another way, limiting background processes may actually hurt more than help. With 3GB of RAM on the Note 4, limiting background processes may not be necessary.

    USB 3.0 to my knowledge does not boost power, like I said already your computer is not going to give it nearly enough power use a wall outlet even for just 15 minutes it will give you 20% added
    I agree. You will not get a full solid charge by charging connected to a laptop, desktop (USB) etc. You need to plug your phone into the included charger into a WALL outlet.

    What do we look for? System almost always ends up higher than screen time for me

    Two things you can do, depending on how many applications you have installed.

    Factory reset and start over, or uninstall your apps and reinstall them one by one.

    Usually if system is your number one resource drain, there is an app constantly running in the background.
